Chandra Makes Its Mark on 2001
Arthur C. Clarke's famous novel, "2001: A Space Odyssey," published in 1968, is, of course, one of the best-known science fiction novels ever written.

Specifically, the following line seemed rather prescient: "[In 2001,] X-ray telescopes kept watch on strange stars that no human
eye would ever see."

science from a universe that is invisible to the unaided eye. Now in its third year of observation, Chandra has observed not only strange
stars as Clarke suggested, but black holes, galaxies, and other cosmic phenomena. Taking a look back, here are some of the highlights of the
past year with Chandra:
